Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electrical connector, and more particularly to a backplane connector having an improved conductive outer shield for engaging with inner shielding plates.

2. Description of the Prior Art

In the manufacture of computers and various other electronic assemblies, daughter boards are commonly connected to mother boards by an electrical connector such as backplane connector. U.S. Pat. No. 6,354,877, issued on Mar. 12, 2002, discloses a backplane connector having an external shield and a plurality of inner shielding plates for reducing crosstalk. A plurality of horizontal eyelets are disposed on an inner surface of the external shield. Each inner shielding plate has a transverse section, a pair of notches located on the transverse section, and a pair of vertical latches extending into the notches and inserting into the horizontal eyelets of the external shield. In this manner, the inner shielding plates are fixed onto the external shield. It would be complicated to assemble the inner shielding plates to the external shield.

U.S. Pat. No. 5,433,618, issued on Jul. 18, 1995, discloses a backplane connector having an external shield defining a plurality of longitudinal slots. The backplane connector also comprises a plurality of inner shielding plates each provided with an extension coupling with the longitudinal slot and projecting beyond a rear surface of the external shield. It is difficult to withstand electrical interference for the inner shielding plates. Additionally, the engagement between the inner shielding plate and the external shield is not reliable, since the extensions project beyond the external shield to have a collision easily.

Hence, an improved electrical connector is needed to solve the above problem.

BRIEF SUMMARY OF THE INVENTION

One object of the present invention is to provide an electrical connector comprising an improved conductive outer shield having a bending portion for more simply and reliably engaging with an inner shielding plate.

The present invention provides an electrical connector comprising an outer shield and a plurality of inner shielding plates mounted to the outer shield. The outer shield has a top wall extending horizontally, a rear wall extending downwardly from the top wall and a bending portion bending inwardly downwardly from an end portion of the rear wall for engaging with the inner shielding plate. The inner shielding plate comprises an extension extending rearwardly therefrom. A plurality of parallel grooves are defined on the bending portion for engaging with the extensions. The bending portion comprises a body section and a medial section connecting the body section to an end of the rear wall, a receiving space being formed outside an outer surface of the body section and below a lower surface of the medial section for receiving the extension of the inner shielding plate.

Advantages of the present invention are to provide an outer shield having bending portion defining a plurality of grooves coupled with the inner shielding plates for simplifying the process of assembling the inner shielding plates to the outer shield. Additionally, the outer shield has a receiving space being formed outside an outer surface of the body section and below a lower surface of the medial section for receiving the extension of the inner shielding plate. The extension would not project beyond the rear wall for avoiding being collided. Therefore, the electrical connector may withstand electrical interference more effectively and enhance the engagement between the outer shield and the inner shielding plates.

Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiments when taken in conjunction with the accompanying drawings.
